Every woman of colour has an important social and cultural history that cannot simply be bleached away or denied by the use of hair straighteners. That’s why I passionately believe that Beyonce’s ignorance of how this betrays her heritage is so insidiously damaging to all peoples of colour.

And this is hardly the first time Beyonce's faced criticism for lightening her hair. Read more opinions -- and tell me yours -- after the jump.

The Internet abounds with negative opinions on Beyonce's various flirtations with bleached hair. At some points, she has worn a blond wig; at others, she's made the look permanent. And plenty have had something to say about it. Here are a few samplings:

She is a black girl. What happened to embracing brown or even black hair ? Beyonce has had black and brown weaves before and has looked simply amazing (even the haters would agree) .... Can black girls wear blonde hair or does it look contrived and fake? -- Charcoal Ink

But now I think maybe Black stars should help African-American women release the hold that blond hair has had on us. It's not a natural hair color. It's not really a good look if you're over 30. It's not particularly healthy for your hair. We don't need the woes that blond hair brings. Black women, let's do something different. -- Teshima Walker, NPR

She didn't go blonde; she went Caucasian. African American women are uniquely beautiful. Why do some of them want to become white? I miss the African American women of the 70's who embraced their natural beauty. Oh, and I'm a white girl, by the way. -- a commenter on Stylelist

What do you think of Beyonce's new look? Is it a betrayal or is it harmless fashion fun?
